If you don't, you google.
First of all, it is clear from the statement that they don't actually know how to breed tritium and are thus doing experiments. Of course it they made
realistic statements about the matter, it is likely that anti-nuclear ignorance squad would begin to object.
Breeding is measured by a breeding ratio that need not be unity. It can be greater than unity of less than unity. As it happens every nuclear reactor has a breeding ratio. It may be possible to recover some neutrons lost by fusion reactors, but on the other hand, cross sections for 14 MeV neutrons are not known for many types of reactions. Most light water reactors operating in the world today, more than 400 industrial scale devices serving hundreds of millions of people, have breeding ratios between 0.7 and 0.9, meaning that they make less than one fissionable nucleus than they consume. The physics of changing the breeding ratio for fission reactors is well understood and has been demonstrated in many places around the world. In fact, such technology is decades old.
The physics of breeding tritium from fusion reactors has never been demonstrated by contrast, and people are only waving their hands saying it
could happen. No fusion reactor has ever generated electricity on this planet, however, and so the matter is just pure speculation.
If you don't know what you're talking about, you can always make stuff up though. You can completely misconstrue and represent what the word "breeding" means, especially if you assume you are speaking to people as poorly educated as yourself.
It is very clear that the statement "Machines after ITER will have to breed tritium from the outset" that the prepositional phrase "after ITER" means that ITER will not do this. Why? Because they have no fucking idea
how to do it. They are merely speculating, hoping that people who aren't too analytical or too knowledgeable will not pick up on what this statement
means.
Fusion power is right now pure hype and wishful thinking, just slightly below the level of the wind and solar fantasy. There's not many people on the planet who believes fusion technology will be available on an exajoule scale in 50 years, although there are obviously lots of people trying to get research dollars by playing on people's unreasonable hopes that
might happen. Of course, a lot of things are more likely, including wholesale destruction of the earth's ecology from climate change, a phenomena that has been observed now for several decades and which is currently accelerating rapidly.
There is only one scalable exajoule scale form of greenhouse gas free energy now on the table. It is great that at least one such form exists, because no matter you read in the idiot journals of Greenpeace, climate change is not starting in 2050. It is happening now. The exajoule scale form of energy about which I speak kills almost no one. It produces some of the lowest cost energy known. Nevertheless there is a stupid squad around whining continuously about it even as they ignore the destruction of earth's atmosphere from dangerous fossil fuel waste. Obviously the form of energy about which I speak is nuclear energy available from fission.
I also predict that
if fusion ever becomes viable, and there's no proof that it will, there will be a stupid squad at the intellectual level of Greenpeace objecting to it.
The question of tritium reserves to start of up a reactor has been exhaustively examined and is right here:
http://fire.pppl.gov/fesac_dp_ts_willms.pdfI've referenced this link before, but it has not resulted in reduced nonsensical mythology about this subject, and I doubt it will do so in this instance.
It shows the ITER, a tiny little demonstration reactor, will consume more almost 2/3 of the world's tritium.
Like I say, if you don't know what you're talking about, make stuff up.
